Drugs they prescribed that Part D paid

$290

Pharmacies billed $290 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

62 generic and 0 brand-name prescriptions · $290 in drug cost · 23 antibiotic prescriptions to 18 people.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
